Duck duck doesn't seem to be living up to its promises (or Startpage, for that matter):
'Oh, and just to be sure… everyone knows that DuckDuckGo (DDG) is also surveillance (and false marketing of privacy). Right? Everyone is aware, we hope. We covered this several times more than half a decade ago.
'For the time being we can recommend SearX (when its pertinent instances are online, e.g. https://srx.sx/ which works at the moment but had uptime issues in recent weeks). It’s Free software as well, not just better at privacy'
